---

Natsu was stuffing his face with food, scarfing down meats and bread and soup as Lucy laid on her bed nearby. The blond was panting, trying to capture her breath as Natsu practically tossed food into his maw. 

The young woman was so exhausted, and Natsu was starving… then again, he was always starving. 

Lucy rested her head on a pillow as she thought about what they had been doing all day. She and Natsu had been going out for hours, since it was daylight out, and now it was night. The sky was dark as the town slumbered. 

The blond was listening to her boyfriend eat, thinking about everything they had done the last few hours, and how he knew about what she had been doing while he was away. She blushed as she raised her voice, calling out to the pink-haired man.

“Are you done, Natsu?” she asked. 

Her answer was a burp, before Natsu spoke. “I’m done eating, if that’s what you want to know.” He walked back to her, wiping a napkin against his lips, before he tossed the tissue aside. “But I’m far from done with you. You need some more training with rough loving! And I’m your teacher!” He smirked.

Lucy took a deep breath and sighed, yet her lips formed a smile on her face. She stretched her arms to the roof of her home, as she sat up on her bed. She looked at Natsu with an amused smile. 

“Someone’s insatiable.”

“Look who’s talking,” he replied with a laugh. 

Lucy wasn’t sure if she was amazed or scared of her boyfriend’s lust for her. She decided to just take it as a compliment for how hot she was and how much he wanted her, as he stood before her and lifted up his hand. 

He grabbed her by her hair, tugging on it, forcing her onto her feet so that their eyes were almost level with one another. She blinked, surprised by the force he was using on her, before her eyes widen as his sharp teeth bit the air in front of her.

Her heart raced as her cheeks became hot. She watched her boyfriend lick his teeth as he whispered, “I’m going to remind you who you belong to.”

Lucy’s body trembled, and she could feel her pussy quivering just from the sound of his voice. She gulped spit down her throat, heart pounding in her chest as she stared into his way. Her sensitive body almost came on the spot, just from the low growl in his voice.

She must have been turning into a masochist…

“O-okay…”

“I’m going to punish you,” he growled. “Make you learn who your one, true Master is.”

“Okay,” she moaned, trembling as she nodded. “I-I’ll accept any punishment you want to give me.” 

Natsu’s smile grew as he looked at her. Just looking at her, he could tell she wanted his cock pounding her pussy. Even after hours of fucking, she wanted more of him. She gave him one last kiss, and she shuddered as his tongue pushed into her mouth.

She gave his tongue a loving suck, before he broke the kiss and forced her down to her knees. Lucy happily obeyed, sinking low until her face was level with his large, semi-hard mound. A tent had formed under his pants, and with one quick tongue, Natsu’s penis was freed, nearly hitting Lucy in the face. 

“Make it hard again,” he ordered her, and Lucy obeyed with an excited nod, licking her lips before she took the cock into her mouth. She moaned around the penis, letting the vibrations go down the long length as she bobbed her head up and down.

Lucy’s tongue dragged along the underside of his cock, tasting every inch that went down her throat. Her eyes fell shut as she found a strange comfort overcome her, consuming her as she licked and sucked on the thick shaft. 

Her nose brushed against his pubic hair as she almost took the entire thing into her mouth. Natsu smiled as he watched her, before he placed his hands on the woman’s head and began to… up her tempo.

Natsu pulled on Lucy’s head, pressing her nose against his crotch as her eyes widened. She let out a muffled cry of shock, before Natsu began to move her head back and forth, face fucking his gorgeous girlfriend faster and harder, showing no mercy as his cock slid in and out of her mouth.

Drool began to drip from her mouth, spilling onto the ground as Lucy’s eyes widened and tears pooled in the corners of her mouth. She felt like she was choking on the hard cock, struggling to breathe, and she loved it. 

She loved the utter lack of control, and the dominance Natsu gave her. Her eyes rolled into her skull as her lips dragged along the veiny shaft, drool and precum dripping onto the ground as her moans and the wet clap of her face fucking filled the room. 

Natsu soon came, not even pulling his cock out of her mouth as he unleashed a stream of semen down her throat. Her body quivered, large breasts jiggling as she sucked in air through her nose. 

She felt the cum pooling in her stomach, and she trembled as it coated the walls of her throat. Natsu pushed Lucy off of his cock with a grin, letting the woman struggle to catch her breath, cum spilling out of her mouth and falling onto the ground, wasted, pooling with her saliva and his precum. 

Natsu then took Lucy in hand and forced her up, making her face the wall with her ass sticking out towards him. 

He took his cock, wet and slick with Lucy’s saliva, and pressed the tip of it against Lucy’s ass. The blond’s eyes widened as she felt the thick, bulbous tip of Natsu’s dick against her asshole, before he began to push it into her. 

“O-oh fuck,” she panted, moaning as the rod was slowly thrusted into her. Natsu only took it slow for the first couple of minutes, letting Lucy adjust to his cock before he began to really fuck her. 

He held her hips in his hands, slamming his body against hers as her ass jiggled with every blow. As he fucked her, Natsu began to speak, grunting with every thrust. “Who did you fuck while I was gone?!” 

“Ahh! G-Gray! Ahh! A-Alzack!” E-Elfman!” He spanked her ass, and she let out a loud cry as she grinned, a fucked silly smile on her face. “S-Scorpio! Gajeel! A-and Romeo!”

“Damn, even Romeo? You are a slut,” he growled, before he grabbed her by her hair and pulled her head back, letting him whisper right against her ear. His hot breath almost burned her skin as she quivered, feeling his cock throb in her ass.

“Were any of them better than me?” he hissed. She could see his eyes staring at her, as cold as his breath was hot. 

“No…” Her heart skipped a beat. “No. No one is better than you.” No hesitation. No stutter. She looked him right in the eye as she answered her boyfriend. She placed her hands on the wall and began to move her body. 

Natsu had stopped fucking her when he asked that last question, and now she was trying to up the pace of his thrusts. She moved her body back and forth, letting the cock fill and fuck her butt as she moaned. 

“No one…”

Natsu grinned, before he suddenly pulled his cock out and grabbed Lucy. He lifted her off of her feet, carrying her to his bed with a grin. Lucy blinked, before he gently laid her down on the soft mattress. 

The pink-haired man then took her body in hand and positioned her so that her whole lower half was up in the air and his cock was aimed right at her pussy. Their eyes locked in on one another, before he shoved his cock into her tight cunt. 

Lucy screamed in pleasure as the cock of her boyfriend, the cock she loved above all others, plowed her pussy. Her fingers dug into the sheets of her bed, and she let out a loud moan as she looked at her boyfriend.

“You better not be lying to me,” he growled, and she shook her head as she let out a loud cry.

Her body was sensitive from already being fucked, and it didn’t take long for her to cum. Her muscles spasmed and her body trembled as her pussy tightened around the cock, squeezing his dick. Natsu let out a loud moan, before he unleashed his sperm into her. 

His seed coated the inside of her pussy, coating the walls of it like he had coated the walls of her throat. Lucy panted, shaking as Natsu fell back, falling onto the bed as he used his great strength to lift her up. 

“Ride me,” he growled, and she obeyed without question. She placed her hands on his body and began to bounce, letting her tits jiggle before his eyes as he spoke. “If you can make me cum before I make you cum, you’re forgiveness. But if not, I’m going to keep punishing you for days.” 

Lucy gulped, trembling as she nodded her head. She took the challenge, bouncing on her boyfriend’s cock as her pussy squeezed his cock. She felt the tip press against the entrance to her womb, and she moaned, panting as she quickened her pace.

She felt the cock stretching out her tight pussy, pressing against the walls as she leaned her head back. She let out a loud moan, and the walls of her cunt clenched around the shaft. It felt so good inside of her, pressing against her G-spot as she moved her hips. 

Lucy soon realized she was going to lose as Natsu smiled at her. She tried to slow down, but it was so hard when her own body wanted to be pounded like a slut. She craved speed, she hungered for Natsu’s cock, she wanted him.

Her body betrayed her as she came on Natsu’s cock, shaking from the climax as it hit her body, turning her into the loser of their little challenge. Natsu gave her a smirk as she trembled on his penis. 

He took her body in his hands and moved his body, lifting her up and slamming into her once more. She mewled, shaking as her pussy held tight around his dick. She screamed as he fucked her, pounding her pussy harder and harder, lifting her up with his strong arms.

Lucy kept the pace going, meeting his standard as he took his hands off of her and placed them on her tits. He squeezed and played with the soft flesh, grinning as she continued to bounce on him like her life depended on it, moaning and crying out his name as stared into his eyes, only to shut them as she came once more. 

Her pussy tightened around his cock again, and this time Natsu filled her pussy with his seed, shooting his cum into her, filling her womb and coating the walls with his thick, sticky nectar. 

“I’ve got one more load in me. Do you think you can take it?” he asked, and Lucy grinned dumbly, nodding her head as the two moved. 

They fell into a missionary position, and he began to fuck her harder and faster than ever. The bed groaned and squeaked below them, shaking from the force of his blows as Lucy allowed him to have his way with her. 

Lucy was seeing stars, eyes wide as drool spilled from her open mouth. The two kissed, lips pressed together as they made out, and their bodies smacked together. Cum spilled out of her pussy and onto the bed as Natsu continued to send her straight to heaven with his cock. 

When Natsu felt his orgasm approaching, he pulled out, letting his seed shoot out all over Lucy’s stomach and onto her wet, cum-filled pussy. The two moaned, panting as Lucy came from the sensation of feeling his seed all over her. 

She loved it. She loved him. She loved this. 

Lucy went limp, panting as she laid on the bed and Natsu grinned. “We should probably go wash off,” he commented, though his eyes on her breasts told her that getting clean was the last thing on his mind. 

She smiled, nodding all the same.

Lucy and Natsu laid in the bathtub together, but even there the loving couple couldn’t keep their hands off of each other. Lucy was riding her naked boyfriend, bouncing on his cock, but at a much slower pace than earlier. She moaned, smiling as her tight pussy clung to his dick, feeling every inch that slid along the wet walls as they bathed. 

She moaned, wrapping her arms around him as the two smiled at one another, relaxing in the serene moment. Their lips pecked at one another as Natsu’s hand stroked his girlfriend’s back, feeling her soft, flawless skin.

They kissed again, lips nibbling one another as Natsu’s hand moved down to give Lucy’s butt a soft squeeze. She squeaked, and giggled into his lips as they continued to kiss, only for the pink-haired man to break it. 

He pulled away, smiling at her as she smiled back with bright, loving eyes. He grinned back at her, a devilish charm to his eyes.

“I’m not going to stop you from sleeping with other guys, Lucy. You can keep doing it if you want, or stop, it doesn’t matter to me.” Lucy blinked at the comment, as Natsu continued. “Just know this. You need to be honest and upfront with me. You need to tell me who you’re sleeping around with. You better not lie to me, because I’ll know,” he smirked, tapping his nose. 

Lucy should have known his sense of smell would be able to pick up other men off of her. She blushed as she nodded her head, before taking one of her hands and stroking his chest with it, playfully drawing circles on him with her fingers.

“And… if I don’t tell you?” 

“Then I’ll punish you,” and to punctuate the statement, he gave her ass a strong slap, making her gasp and shudder from the blow.

Lucy shook her ass side to side after the blow, smiling as she nodded her head in agreement. Part of her almost wanted to be punished, but that was a debate for another day as she leaned in to kiss her boyfriend once more. 

Their lips met and Lucy moaned as she held her boyfriend against her body, letting her large breasts push against him, nipples dragging along his skin. 

As the two kissed, Lucy thought of all the sex she’ll have with Natsu, Gray, and all the other members of their Guild. Guys, girls, she didn’t particularly care, she just wanted to have a good time.

Lucy smiled as she cuddled up with her boyfriend in the warm, serene water. She couldn’t wait until tomorrow where she’d go back on the hunt for a good time...
